Hello I have a Pioneer vsx-d712 receiver and i've had it for about 3 years. About 2 months ago I got some new speakers I got Polk Audio Rm10 and they worked great at first. Now after about a month my reciever started shutting off and saying overload while watching movies and playing video games and I don't have it turned up very loud. I was wondering if anyone could please help me any help would be greatly appreciated.
